*	Lab 6:	Question 6
*
*	Description:
*	Write a Java program, called AsciiDifference that contains a static method called difference() 
*	that accepts two Strings as the input parameters and returns the difference in the sum of ASCII 
*	values of the two Strings as an integer value. The input parameters should be read in from the 
*	user in the main method and passed to the difference() method. The main method should print 
*	returned integer to the screen.
*
*	Sample Input:	ireland
*					IRELAND
*
*
*	Sample Output:	224
*
*	Explanation:
*	String s1 = "ireland"; String s2 = "IRELAND"; 
*	The sum of ASCII Values for s1 = 735 The sum of ASCII Values for s2 = 511 
*	The difference between s1 and s2 = 224
*
*	Algorithm:
*	Step 1:	Two user input as two separate Strings
*
*	Step 2: Pass Strings to difference() method
*			A):	Using a for-loop, convert each character of a String to its ascii value and sum the total
*			B)	Compute the difference between these sums
*			C)	Return the result to main
*
*	Step 3: Print the result
